What is the primary mechanism by which the body regulates its acid-base balance during respiratory acidosis?

A Renal compensation through increased excretion of hydrogen ions
B Respiratory compensation through increased ventilation ✓
C Hemodynamic compensation through increased cardiac output
D Metabolic compensation through increased production of bicarbonate

Explanation

During respiratory acidosis, the body compensates by increasing ventilation to blow off more CO2, thereby reducing the acidity of the blood.

Mnemonic

Respiratory acidosis → Respiratory compensation
